The word nishka is often used in the Rig-Veda with a connotation that is by no means clear. In some passages it means money, in others it implies a golden ornament for the neck. The two interpretations are not necessarily contradictory, for in India pieces of gold which serve as money have been used as ornaments for the neck from times immemorial.
On the other hand, there are distinct references to voyages by sea, though of course the words used may mean rivers only, and not the sea. The shipwreck of Bhujyu and his deliverance by the gods Asvins, is constantly alluded to, and the god Varuna is said to know the paths of the birds through the sky and the paths of the ships over the sea. Allusion is also made to the "people who, desiring to acquire wealth, pray to the sea before undertaking a voyage"; and another passage runs:—
"When Varuna and I went on a boat and took her out to sea, I lived in the boat floating on the water and was happy in it, rocking gracefully (on the waves)."
While there are these and other distinct allusions to voyage, there is absolutely no prohibition against it in the Rig-Veda, such as prevailed in later times and still holds among the orthodox of India.
